Shogun 2: Total War Info Leaks

[alien space marine]

A concern I have about it being in Japan, Is that since all the factions are Japanese are they all going to be identical to each other?

and will they restore the family tree concept that was removed in the last installment?

Something I disliked about Empire and Napoleon is that they didnt let you rename cities and regions like you could in RomeTW barbarian invasion.
